XHR-150型塑料洛氏硬度计采用自动加卸试验力机构，装有可调总试验力保持时间的电位器，试验力变换由变荷手轮的旋转而获得，所以操作简便迅速，除度盘对零外，没有人为的操作误差，具有很高的灵敏度，稳定性。
    适用于工厂车间和实验室。             

    XHR-150 type of plastic Rockwell hardness tester used of the automatic load or uninstall test force, have a adjustable total test force dwell time potentiometers,the test force transformation from the rotation was the Pressure Selecting Handwheel, so simple rapidly, In addition to the Panel at zero, no human operator error, with very high sensitivity, stability.            
    Apply to the factory floor and laboratories.
